Interface Device

The primary functions for this device are to

1. Provide time-division multiplexing (TDM) functions to the LCD

and VGA color data bus.

2. Provide level shifting feature for the 2.5V input (Cyclone III FPGA)

and 3.3V required by many of the interface chips.

This package has 272 user I/Os and comes in a 324-pin Fine-Line BGA

package. Table 2–3 lists Max II device features.
